Overview of Solar Technologies

Solar Hot Water - Solar hot water is the most cost effective solar technology currently available. Generating hot water typically accounts for 20-25% of a household's energy usage. Solar hot water can reduce this energy expenditure by 80% or more. For some businesses where hot water use is particularly high, a solar hot water system can be a very good investment. Installing a solar electric array without the presence of a solar hot water system, does generally not make sense from a financial perspective.

Solar Electricity (Photovoltaics) Grid Tied - In a grid-tied solar electric array, the electricity produced from an array of solar panels is converted to energy that can be fed back to the grid. Your electric usage then gets subtracted by what is produced from your solar array, and if that amount is a negative number then your meter runs backwards. At current prices, customers that purchase grid tie photovoltaic systems do so for ideological reasons much more than financial ones.

Solar Electricity (Photovoltaics) Off Grid - Off grid solar electricity involves getting power from photovoltaic solar panels and storing it in a bank of batteries. The cost effectiveness of such a system depends on how far away the electric grid is, and how much power is needed.

Solar Pool Heating - If you are heating a swimming pool with something other than solar, you already know how expensive it can be. If you are not heating your pool, then solar hot water can extend number of months that a pool is comfortable to swim in. A solar pool heater can be considered a sound investment that will pay for itself faster than nearly all other solar products available.
